APPARATUS FOR TREATING GASES.

Application filed October 24, 1919. Serial No. 333,115.

To all whom t may concern:

Be it known that I, OsoAR-L. BARNEBEY, a citizen of the United States, residing at Cleveland, in the county of Cuyahoga and State of Ohio, have invented certain new and useful Improvements in Apparatus for Treating Gases, of which the following is a specification.

The present invention relates to apparatus for heating to hi h temperature steam or other gaseous ilui s and has among its objects the production of an apparatus that is simple in construction, efficient, easy of repair, and one that does not readily deteriorate under conditions of operation.V

With these and other objects in view the invention comprises an apparatus made up of a number of tubes for the passage of the gases to be heated arranged in a suitable casing in such manner that they may be easily removed when necessary and in such manner as to be efficiently heated.

For certain purposes it has been found necessary to heat gases, particularly steam, to temperatures over 600 C., under slight pressure. For superheating steam, iron heaters which are enerally used deteriorate rapidly when app ied to high temperature work, due to chemical reaction resulting in corrosion.

Only such materials into: which oxidation cannot penetrate can be used for this purpose. In short, the material must maintain its integrity and rigidity to withstand the e'ects of both high temperature and some pressure, No metallic superheater on the market satisfies these requirements;

The alloys found suitable for this purpose are:

Iron containing 0.1% to 20% of metallic copper. l

These alloys are cast into the form of pipes which can be used singly or connected in multiple. The pipes are arranged in such a manner as to give maximum utilization of the heat applied thereto. When used in multiple the ends of the pipes are joined by the use of high melting-point flanges and U-bends, flanges, unions and elbows; U-bends and appropriate bushings or any other convenient form of connection. A highly refractory material such as asbestos or high melting-point metal or alloy rings may be used as packing to give tight connections. Likewise only high meltingpoint metal or alloy can be used for bolts,- nuts, ete.

The invention is more easily understood by reference to the accompanying drawings in which- Fig. 1 is a longitudinal cross-sectional elevation of the apparatus, v

Fig. 2 is a transverse view partly in cross-section.

Fig. 3 shows a detail of construction.

The walls of thefurnace 1 are built of ordinary brick with fire-brick linin Intermediate along the floor of the igurnace are a series of transverse partitions 2 and alternate checkerwork partitions 3. Alundum chips 4 furnish the surface area for surface combustion. Fuel is introduced through the burners 5. The fuel is lighted through peep-holes 6 which also serve for observation.

The high melting-point non-oxidizable allo tubes 7 furnish the essential heating sur ace for the superheating of steam or other gases. The companion langes 8 and 9, threaded respectively upon ends of tubes 7 and 11 are held firmly together by special alloy bolts 10, Asbestos or other suitable packing is used for gaskets between 8 and 9. The U-bends 11 connect the successive pipes 7 in series. An arched cover is best adapted to apparatuses of this type. The gases to be heated ente-rthru the assage (13) and leave by way of passage 12).

The present invention is not limited to the specic details set forth in the foregoing examples which should be construed as illustrative and not by way of limitation, and in view of the numerous modifications .which may be effected therein without departing from the spirit and scope of this invention, it is desired that only such limitations be imposed as are indicated in the appended claims.

I claim as my invention:

l. An apparatus for highly superheating Ano having all of -thoparts in contact with the super-heated gases of iron alloy containing a, small quantity of copper and possessing high resistance against corros1on`and- 5 deterioration by superheated vgasses underpressure. v i
